Gtk2::Ex::FormFactory::DialogButtons - Standard Ok, Apply, Cancel Buttons
clicked_hook_before => CODEREF,
clicked_hook_after => CODEREF,
This class implements a typical Ok, Apply, Cancel buttonbox in
a Gtk2::Ex::FormFactory framework.
If you associate an application
object attribute the value needs to be a hash which may contain
the keys ok, apply and cancel to control the activity of
the correspondent buttons. Wheter inactive buttons should be
render insensitive or invisible is controlled by the
Gtk2::Ex::FormFactory::Widget attribute <B>inactiveB>.
By default the following methods of the associated
Gtk2::Ex::FormFactory instance are triggered:
No Cancel and Apply buttons are generated if the associated
Gtk2::Ex::FormFactory has the <B>syncB> attribute set. A synchronized
FormFactory applies all changes immediately to the underlying objects,
so there is no easy way of implementing the Apply and Cancel buttons.
You can implement these by your own e.g. by registering a copy of
your object to Gtk2::Ex::FormFactory::Context and hook into the
button clicks using the <B>clicked_hook_beforeB> attribute described
Attributes are handled through the common get_ATTR(), set_ATTR()
style accessors, but they are mostly passed once to the object
constructor and must not be altered after the associated FormFactory
For more attributes refer to Gtk2::Ex::FormFactory::Widget.
<B>clicked_hook_beforeB> = CODEREF(ok|apply|cancel)
Use this callback to hook into the clicked signal handler of the
buttons. Argument is the name of the button actually clicked (ok, apply
or cancel). If the callback returns TRUE, Gtk2::Ex::FormFactorys
default handler for the button is called afterwards. Return
FALSE to prevent calling the default handler.
<B>clicked_hook_afterB> = CODEREF(ok|apply|cancel)
This callback is called <B>afterB> the default handler. This is useful
if you want to exit your program cleanly if your main dialog was
closed. First Gtk2::Ex::FormFactory closes the dialog window for you,
doing all necessary cleanup stuff. Afterward you simply call
Gtk2->main_quit to exit the program.
The callbacks return value doesnt matter.
